I need help in this quiz, Please answwr fast and 100% correct

Assignment #7, due Thursday, March 8, 15 pts. Conventional clastic reservoir rocks are usually deposited in: 1. (Choose one) high energy conditions low energy conditions either 2. (Choose one) oxygen-rich conditions oxygen-poor condieither 3. (6 pts) Choose the sedimentary structures, commonly found in clastic sands, that indicate a current bedding planes bioturbation cross-bedding delta top set and foreset beds herringbone cross-bedding parallel laminations ripples and ripple laminations scour features such as channels sole markings like flute casts and groove casts stylölites 4. (7 pts) Choose the common characteristics of conventional clastic reservoir abundance of fossils fractures graded bedding growth framework porosity high capillary entry pressure high percentage of organic matter intergranular porosity intraparticle porosity low capillary entry pressure low percentage of organic matter massive bedding parallel laminated mud parallel laminated sand

Explanation / Answer

Answer1: High energy

see clastic reservoir means deposits of broken sediment derived from some source rock so we need transportation( rivers) for this so they must be deposited in high energy conditions.

they can deposited in both oxygen rich and poor but oxygen poor zone is most probable because sediment remain in water which cutoff their contact from air.

answer 2:

cross bedding, herringbone cross-bedding, ripple and ripple laminations, scour features,.sole marks

answer 3:

abundance of fossil

fractures

growth framework porosity

low organic percentage

intergranular porosity

intraparticle porosity

sand size grains

massive bed

poorly to well sorted both
